Ankle injuries are the most common injury to volleyball players and responsible for the most lost playing time. Ankle sprains should be immobilized for as short as time as possible to allow for quicker rehabilitation.nterior Cruciate Ligament (ACL) Injury. Like ankle sprains, most ACL injuries in volleyball players occur when a player lands awkwardly after jumping. Usually ACL tears are associated with a pop and immediate knee swelling.
No, H2CO3 is an aquous solution of carbon dioxide gas (CO2). It can also be 'written' as (CO2+H2O) or (CO2.H2O) or (CO2,aq) = hydrate of carbon dioxide and its chemical name â¦ : carbonic acid.hat we call carbonic acid is actually CO2 dissolved in water in equilibrium with H+ and HCO3^-. Carbonic acid is a weak acid, and so you might think that there would be nonionized H2CO3 molecules.
Sulphates are usually soluble in water except for Ag2SO4, BaSO4, CaSO4 and PbSO4 (lead sulphate).Hope that helps (: PbSO4 is sparingly soluble in water, its solubility at 298K is about 1.4E-4 mol/L, a very small value. So its not insoluble, it just has a very small solubility.lthough the anion (SO4 2-) is found on the solubility chart, you must remember that there are exceptions i.e. the silver group (Silver ion-A â¦ g+, Mercury (I) ion-Hg2 2+, and Lead (II) ion-Pb 2+) Since the Lead (II) cation is in the chemical formula Lead (II) Sulfate (PbSO4), it will be INSOLUBLE in water.
